  • sending HTML email with a variable in the URL

    - by Rob Crouch
    I am using the following script to send a dynamic page (php) as a html email... the page being emailed uses a variable in the URL to determine what record is shown from a database <? $evid = $_GET['evid']; $to = '[email protected]'; $subject = 'A test email!'; // To send HTML mail, the Content-type header must be set $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; // Put your HTML here $message = file_get_contents('http://www.url.co.uk/diary/i.php?evid=2'); // Mail it mail($to, $subject, $message, $headers); ?> as you can see the html file being emailed has a evid variable... if i set this to $evid and try to send the variable when running the current script I get an error... does anyone know of a way round this? hope i explained that clear enough Rob

  • Hibernate + Spring : cascade deletion ignoring non-nullable constraints

    - by E.Benoît
    Hello, I seem to be having one weird problem with some Hibernate data classes. In a very specific case, deleting an object should fail due to existing, non-nullable relations - however it does not. The strangest part is that a few other classes related to the same definition behave appropriately. I'm using HSQLDB 1.8.0.10, Hibernate 3.5.0 (final) and Spring 3.0.2. The Hibernate properties are set so that batch updates are disabled. The class whose instances are being deleted is: @Entity( name = "users.Credentials" ) @Table( name = "credentials" , schema = "users" ) public class Credentials extends ModelBase { private static final long serialVersionUID = 1L; /* Some basic fields here */ /** Administrator credentials, if any */ @OneToOne( mappedBy = "credentials" , fetch = FetchType.LAZY ) public AdminCredentials adminCredentials; /** Active account data */ @OneToOne( mappedBy = "credentials" , fetch = FetchType.LAZY ) public Account activeAccount; /* Some more reverse relations here */ } (ModelBase is a class that simply declares a Long field named "id" as being automatically generated) The Account class, which is one for which constraints work, looks like this: @Entity( name = "users.Account" ) @Table( name = "accounts" , schema = "users" ) public class Account extends ModelBase { private static final long serialVersionUID = 1L; /** Credentials the account is linked to */ @OneToOne( optional = false ) @JoinColumn( name = "credentials_id" , referencedColumnName = "id" , nullable = false , updatable = false ) public Credentials credentials; /* Some more fields here */ } And here is the AdminCredentials class, for which the constraints are ignored. @Entity( name = "admin.Credentials" ) @Table( name = "admin_credentials" , schema = "admin" ) public class AdminCredentials extends ModelBase { private static final long serialVersionUID = 1L; /** Credentials linked with an administrative account */ @OneToOne( optional = false ) @JoinColumn( name = "credentials_id" , referencedColumnName = "id" , nullable = false , updatable = false ) public Credentials credentials; /* Some more fields here */ } The code that attempts to delete the Credentials instances is: try { if ( account.validationKey != null ) { this.hTemplate.delete( account.validationKey ); } this.hTemplate.delete( account.languageSetting ); this.hTemplate.delete( account ); } catch ( DataIntegrityViolationException e ) { return false; } Where hTemplate is a HibernateTemplate instance provided by Spring, its flush mode having been set to EAGER. In the conditions shown above, the deletion will fail if there is an Account instance that refers to the Credentials instance being deleted, which is the expected behaviour. However, an AdminCredentials instance will be ignored, the deletion will succeed, leaving an invalid AdminCredentials instance behind (trying to refresh that instance causes an error because the Credentials instance no longer exists). I have tried moving the AdminCredentials table from the admin DB schema to the users DB schema. Strangely enough, a deletion-related error is then triggered, but not in the deletion code - it is triggered at the next query involving the table, seemingly ignoring the flush mode setting. I've been trying to understand this for hours and I must admit I'm just as clueless now as I was then.

  • Cannot read values from [NSUserDefaults standardUserDefaults] after synchronize

    - by Nonlinearsound
    In the Application Delegate didFinishLaunching method, I am using the following code to build up a new NSDictionary to be used as the new settings bundle for the user: NSNumber *testValue = (NSNumber*)[[NSUserDefaults standardUserDefaults] objectForKey:@"settingsversion"]; if (testValue == nil) { NSNumber *numNewDB = [NSNumber numberWithBool:NO]; NSNumber *numFirstUse = [NSNumber numberWithBool:YES]; NSDate *dateLastStatic = [NSDate date]; NSDate *dateLastMobile = [NSDate date]; NSNumber *numSettingsversion = [NSNumber numberWithFloat:1.0]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObjectsAndKeys: numNewDB, @"newdb", numFirstUse, @"firstuse", numSettingsversion, @"settingsversion", dateLastStatic, @"laststaticupdate", dateLastMobile, @"lastmobileupdate", nil]; [[NSUserDefaults standardUserDefaults] registerDefaults:appDefaults]; [[NSUserDefaults standardUserDefaults] synchronize]; } Later in another ViewController I am trying to read back a value from that same Dictionary, saved as the NSUserDefaults - well at least I thought it would, but I don't get any valid object pointer for the desired member lastUpdate back there: in .h file: NSDate *lastUpdate; in the .m file in a member function: lastUpdate = (NSDate *)[[NSUserDefaults standardUserDefaults] objectForKey:@"laststaticupdate"]; Even, if I print out the content of [NSUserDefaults standardUserDefaults] I only get this: 2010-04-29 15:13:22.322 myApp[4136:207] Content of UserDefaults: <NSUserDefaults: 0x11d340> This leads me to the conclusion that there is no standardUserDefaults dictionary somewhere in memory or it cannot be determined as such a structure. Edit: Every time, I restart the app ión the device, the check for testValue is Nil and I am building up the dictionary again but after one run it should be persistent on the Phone, right? Am I doing something wrong somewhere in between? I have the feeling that I yet didn't really understand how to load and save settings persistent for a certain application on the iPhone. Is there anything I have to do additionally to this? Integrating a settings.bundle in XCode or saving the dictionary manually to the Documents folder? Can someone help me out here? Thanks a lot!

  • Encoding MySQL text fields into UTF-8 text files - problems with special characters

    - by Matt Andrews
    I'm writing a php script to export MySQL database rows into a .txt file formatted for Adobe InDesign's internal markup. Exports work, but when I encounter special characters like é or umlauts, I get weird symbols (eg Chloë Hanslip instead of Chloë Hanslip). Rather than run a search and replace for every possible weird character, I need a better method. I've checked that when the text hits the database, it's saved properly - in the database I see the special characters. My export code basically runs some regular expressions to put in the InDesign code tags, and I'm left with the weird symbols. If I just output the text to the browser (rather than prompt for a text file download), it displays properly. When I save the file I use this code: header("Content-disposition: attachment; filename=test.txt"); header("Content-Type: text/plain; charset=utf-8"); I've tried various combinations of utf8_encode() and iconv() to no avail. Can anybody point me in the right direction here?

  • how to tile 3D mesh with image brush in XAML

    - by MC9000
    I have a 2D square in a ViewPort3D that I want to do a tiling of an image (like a checkerboard or flooring with "tiles" effect). I've created an image brush (the image is 50x50 pixels, the surface 250x550 pixels) and a viewport (trying to follow MS's site - though their example is for 2D), but only 1 of the colors in the "tile" image shows up and no tiling is seen. I can't find a single example on the Internet and MS's site has no info (that I can find) on 3D XAML anywhere, so I'm stumped as how to actually do this. <Viewport3D> <Viewport3D.Camera> <PerspectiveCamera Position="125,790,120" LookDirection="0,-.7,-0.25" UpDirection="0,0,1" /> </Viewport3D.Camera> <ModelVisual3D> <ModelVisual3D.Content> <Model3DGroup> <AmbientLight Color="white" /> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="0,0,0 250,0,0 250,550,0 0,550,0 " TriangleIndices="0 1 3 1 2 3 "/> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <ImageBrush ViewportUnits="Absolute" TileMode="Tile" ImageSource="testsquare.gif" Viewport="0,0,50,50" Stretch="None" ViewboxUnits="Absolute" /> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> </GeometryModel3D> </Model3DGroup> </ModelVisual3D.Content> </ModelVisual3D> </Viewport3D>

  • Windows PE - Where and how are strings stored if not in resources?

    - by sdadsas
    Usually strings (like content/titles of dialog boxes) in .exe files are stored in some sort of resources. But in some recent exes I disassembled/resource-inspected I couldn't find any resources containing the string but it was somehow hardcoded with db's into the program source code. How can I extract and modify strings directly located in the program? I assume those are just the equivalent to const char*s in C++? Why would someone not "outsource" the contents of dialog boxes, menus, etc?

  • REST API error return good practices

    - by Remus Rusanu
    I'm looking for guidance on good practices when it comes to return errors from a REST API. I'm working on a new API so I can take it any direction right now. My content type is XML at the moment, but I plan to support JSON in future. I am now adding some error cases, like for instance a client attempts to add a new resource but has exceeded his storage quota. I am already handling certain error cases with HTTP status codes (401 for authentication, 403 for authorization and 404 for plain bad request URIs). I looked over the blessed HTTP error codes but none of the 400-417 range seems right to report application specific errors. So at first I was tempted to return my application error with 200 OK and a specific XML payload (ie. Pay us more and you'll get the storage you need!) but I stopped to think about it and it seems to soapy (/shrug in horror). Besides it feels like I'm splitting the error responses into distinct cases, as some are http status code driven and other are content driven. So what is the SO crowd recommendation? Good practices (please explain why!) and also, from a client pov, what kind of error handling in the REST API makes life easier for the client code?

  • Render action return View(); form problem

    - by Roger Rogers
    I'm new to MVC, so please bear with me. :-) I've got a strongly typed "Story" View. This View (story) can have Comments. I've created two Views (not partials) for my Comments controller "ListStoryComments" and "CreateStoryComment", which do what their names imply. These Views are included in the Story View using RenderAction, e.g.: <!-- List comments --> <h2>All Comments</h2> <% Html.RenderAction("ListStoryComments", "Comments", new { id = Model.Story.Id }); %> <!-- Create new comment --> <% Html.RenderAction("CreateStoryComment", "Comments", new { id = Model.Story.Id }); %> (I pass in the Story id in order to list related comments). All works as I hoped, except, when I post a new comment using the form, it returns the current (parent) View, but the Comments form field is still showing the last content I typed in and the ListStoryComments View isn’t updated to show the new story. Basically, the page is being loaded from cache, as if I had pressed the browser’s back button. If I press f5 it will try to repost the form. If I reload the page manually (reenter the URL in the browser's address bar), and then press f5, I will see my new content and the empty form field, which is my desired result. For completeness, my CreateStoryComment action looks like this: [HttpPost] public ActionResult CreateStoryComment([Bind(Exclude = "Id, Timestamp, ByUserId, ForUserId")]Comment commentToCreate) { try { commentToCreate.ByUserId = userGuid; commentToCreate.ForUserId = userGuid; commentToCreate.StoryId = 2; // hard-coded for testing _repository.CreateComment(commentToCreate); return View(); } catch { return View(); } }

  • Unit testing and mocking email sender in Python with Google AppEngine

    - by CVertex
    I'm a newbie to python and the app engine. I have this code that sends an email based on request params after some auth logic. in my Unit tests (i'm using GAEUnit), how do I confirm an email with specific contents were sent? - i.e. how do I mock the emailer with a fake emailer to verify send was called? class EmailHandler(webapp.RequestHandler): def bad_input(self): self.response.set_status(400) self.response.headers['Content-Type'] = 'text/plain' self.response.out.write("<html><body>bad input </body></html>") def get(self): to_addr = self.request.get("to") subj = self.request.get("subject") msg = self.request.get("body") if not mail.is_email_valid(to_addr): # Return an error message... # self.bad_input() pass # authenticate here message = mail.EmailMessage() message.sender = "[email protected]" message.to = to_addr message.subject = subj message.body = msg message.send() self.response.headers['Content-Type'] = 'text/plain' self.response.out.write("<html><body>success!</body></html>") And the unit tests, import unittest from webtest import TestApp from google.appengine.ext import webapp from email import EmailHandler class SendingEmails(unittest.TestCase): def setUp(self): self.application = webapp.WSGIApplication([('/', EmailHandler)], debug=True) def test_success(self): app = TestApp(self.application) response = app.get('http://localhost:8080/[email protected]&body=blah_blah_blah&subject=mySubject') self.assertEqual('200 OK', response.status) self.assertTrue('success' in response) # somehow, assert email was sent

    I am in the process of building a system where i need to notify a Window Service a .net based application in case of any change in the DB table (Insert , Update , Delete). I know this can be done with the ADO.NET Events in SQL. Is there any common solution for Oracle and SQL which can provide this kind of notifications. This needs to happen as and when the update happens on real time basis.

  • Problem consuming Exchange Web Service 2010 with jax-ws metro

    - by Johan Karlberg
    I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.

  • How to disable vertical bounce/scroll on iPhone in a mobile web application

    - by Kasper Skov
    As the title says, i need to disable vertical bounce on iphone on my mobile web form application. Ive tried alot of different things, but most of them disables my form or horizontal scroll and bounce as well. Any ideas? Im using jquery.mobile btw :) Update: I actually managed to get the code from the first answer working somewhat: function stopScrolling( touchEvent ) { touchEvent.preventDefault(); } document.addEventListener( 'touchstart' , stopScrolling , false ); document.addEventListener( 'touchmove' , stopScrolling , false ); The reason why I couldnt get it to work in the first place, was that there actually was some margin on my body (stupid me). But. As the layout is fluid and im using jquery.mobile and have <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> in the header (I think) it doesnt work properly. The page is zoomed out (view from like a desktop browser) and zooming is disabled. Without the code, the page scales perfectly right from an 50" tv to the smallest nokia on the planet. Am I doing something wrong? Im starting to think the problem is caused by the body/content somehow being over 100% of the viewport. No idea how though.

  • Most efficient way to store list structure in XML

    - by Mike
    Starting a new project and was planning on storing all of my web content in XML. I do not have access to a database so this seemed like the next best thing. One thing I'm struggling with is how to structure the XML for links (which will later be transformed using XSLT). It needs to be fairly flexible as well. Below is what I started with, but I'm starting to question it. <links> <link> <url>http://google.com</url> <description>Google</description> <link> <link> <url>http://yahoo.com</url> <description>Yahoo</description> <links> <url>http://yahoo.com/search</url> <description>Search</description> </link> <link> </links> That should get transformed into Google Yahoo Search Perhaps something like this might work better. <links> <link href="http://google.com">Google</link> <link href="http://yahoo.com">Yahoo <link href="http://yahoo.com/search">Search</link> </link> </links> Does anyone perhaps have a link that talks about structuring web content properly in XML? Thank you. :)

  • Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

    - by Alexey Romanov
    I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?
